The ARL Division of Neurobiology (ARLDN) is an academic and organized-research unit devoted to education and research on the development, organization, evolution, and function of nervous systems.

Research in the ARLDN includes projects based on the disciplines of cellular, developmental, molecular and systems neurobiology, neuroethology, and neurogenetics, targeting contemporary issues such as intra- and intercellular signaling, synaptic mechanisms, development of the central nervous system, information processing in sensory systems, insects as vectors of disease, mental retardation, evolution of neural systems, and biorobotics.
